John Lennon died almost 30 years ago, yet the FBI still has him on its radar. Lennon was fingerprinted in 1976 when he was applying for U.S. citizenship. The card was set to be auctioned when a G-man showed up outside Gotta Have It! in New York City. The FBI wanted the card pulled and finally got a subpoena and the fingerprints. “If it was anybody else’s fingerprint card,” the owner of the store said, “I wouldn’t hear from anybody.”

Chicago Cubs slugger Sammy Sosa maintained he never meant to use that illegal bat in the 2003 game against the Tampa Bay Devil Rays. He had it to put on a hitting display before the game and picked it up accidentally. Be that as it may, Sosa had the misfortune of the bat cracking during the game, exposing cork in the barrel. The barrel then went missing. It turns out that Cubs pitcher Mike Remlinger picked it up and kept it all these years. Remlinger is now selling the infamous keepsake, and the auction house is guessing it may go for more than $10,000.
